Genghis basically said it, it also gives you the opportunity to sneer at Pilots with no tailwheel experience and talk about their "training wheel"
(all in jest of course)
The reality is though that tailwheel teaches you some valuable handling but also it gives you some valuable experience in go-around decision making, one of the things you learn quite rapidly is that it's much harder to recover a rubbish approach and as such you are more comfortable with the concept of going around being a smart decision. There's a very common thought amongst inexperienced pilots that every approach is followed by a landing, no matter how crappy the approach is. You simply cannot afford to have this attitude in a tailwheel aircraft
